A server for synthesizing a video stream includes: a first single video stream receiving part which receives a first single video stream including a plurality of video data, from a prior video stream synthesizing server; an advertisement video stream receiving part for receiving an advertisement video stream from an advertisement server; a video stream synthesizing part for generating a second single video stream, by synthesizing the first single video stream and the advertisement video stream; and a transmission part for transmitting the second single video stream to a device.

Description

TECHNICAL FIELD [0001] The present invention relates to a server and a device for synthesizing a local advertisement, and a server for synthesizing a video stream,

A server and an apparatus for composing local advertisements, and a server for composing a plurality of video streams.

A general broadcast service transmits a channel using a multicast or broadcast transmission method. Since all viewers watch the same screen, it is difficult to provide a target video advertisement according to viewer tendencies, regions, and the like. Conventionally, local advertisements are provided through a method of providing images or texts through a separate session and overlaying the channels over decoded channels by a terminal such as a set-top box or a smart TV In this case, you can not provide video ads. Korean Patent Publication No. 2012-0071451 discloses a method of providing a target type advertisement to a terminal supporting a separate EPG (Electronic Program Guide) in connection with a method of providing a customized advertisement.

Meanwhile, recently, TV apparatuses that display two or more broadcast channels on a single broadcast screen using PIP (Picture in Picture) have appeared. However, such TV apparatuses receive two or more broadcast signals, decode them through a decoder corresponding to the number of broadcast signals embedded in the TV apparatus, and display them on the screen. A larger number of decoders are needed to display more broadcast screens on a single screen. Therefore, there is a need for a method for displaying a large number of broadcast screens on one screen without increasing the number of decoders.

We want to provide video-targeted advertising without changing the existing broadcasting platform. And a target video advertisement is inserted on a broadcast image at a local node receiving the multicast broadcast image. It is to be understood, however, that the technical scope of the present invention is not limited to the above-described technical problems, and other technical problems may be present.

According to an aspect of the present invention, there is provided an apparatus for receiving a first video stream from a previous video stream composition server, the first video stream including a plurality of video data, A single video stream receiving unit for receiving the advertisement video stream from the advertisement server, an advertisement video stream receiving unit for receiving the advertisement video stream from the advertisement server, a video stream synthesizing unit for generating the second single video stream by synthesizing the first single video stream and the advertisement video stream, And a transmission unit for transmitting the stream to the device

According to another embodiment of the present invention, there is provided a method comprising: receiving a first single video stream from a previous video stream composition server, the first single video stream including a plurality of video data of a plurality of broadcast channels; A method comprising: receiving an advertising video stream from a server; generating a second single video stream by combining a first single video stream and an advertising video stream; and transmitting a second single video stream to the device Method can be provided.

According to another aspect of the present invention, there is provided a broadcast video stream receiving apparatus for receiving a broadcast video stream corresponding to a broadcast channel from a broadcast platform server, an advertisement video stream receiving unit for receiving an advertisement video stream from the advertisement server, A video stream composition server for generating a single video stream by combining video streams, and a transmission unit for transmitting a single video stream to a second video stream composition server or a device.

According to another embodiment of the present invention, there is provided a method for receiving an advertisement video stream, the method comprising: receiving a broadcast video stream corresponding to a broadcast channel from a broadcast platform server; Generating a single video stream by combining the broadcast video stream and the advertisement video stream, and transmitting the single video stream to the second video stream composition server or the device.

According to any one of the above-mentioned means for solving the above-mentioned problems, the video target advertisement can be provided without changing the existing broadcasting platform. It is possible to insert a target video advertisement on a broadcast image and provide the target video advertisement to the device at the local node receiving the broadcast image transmitted by multicast. The target video advertisement is provided through the unicast method at the local node to which the device is connected, thereby reducing the bandwidth waste of the network. It is possible to diversify the import model by providing the existing channel service to the paid subscriber and by inserting the video advertisement into the free service user. It is possible to provide a dynamic advertisement based on a video rather than an image-oriented advertisement. Multiple configurations of the server allow you to organize different types of movies on a single screen. Since the video content is included in the broadcast screen and is provided as a single stream, the target advertisement service can be provided without replacing the existing low-end terminal.

For example, the video stream composition unit 103 may synthesize an advertisement video stream related to a local advertisement in a first single video stream in which a broadcast video stream and an advertisement video stream are synthesized through a previous video stream composition server.

The video stream composition unit 103 may generate a header of the advertisement video data of the advertisement video stream, and may synthesize the first single video stream, the generated header, and the advertisement video data to generate the second single video stream. At this time, the generated header may include at least one of position information and size information of the advertisement image data in the second single video stream. For example, the video stream composition unit 103 may form a screen of the first single video stream and the advertisement video stream based on the metadata.

The first single video stream may include a first broadcast video data of a first broadcast stream, a first header of a first broadcast video data, a second broadcast video data of a second broadcast stream, and a second broadcast video data of a first broadcast stream among a plurality of broadcast streams corresponding to the plurality of broadcast channels. And a second header of the second broadcast image data. The video stream composition unit 103 may include a first header, a first broadcast image data, a second header, a second broadcast image data, a header for the advertisement image, The second single video stream can be generated by combining the advertisement video data

The video stream composition unit 103 determines the first broadcast video data as the first slice data of the second single video data, determines the first header as the first slice header of the first slice data, Determines the second header as the second slice header of the second slice data, determines the advertisement image data as the third slice data of the second single image data, And determine the generated header as the third slice header of the third slice data.

In this case, the video stream synthesizing unit 103 synthesizes the first slice header, the first slice data, the second slice header, the second slice data, the third slice header, and the third slice data, Can be generated.

The video stream composition unit 103 may determine the first slice data, the second slice data, and the third slice data based on FMO (Flexible Macroblock Ordering) in synthesizing the second single video stream. The first slice data, the second slice data, and the third slice data may be slice data of a predetermined frame of the second single image data.

The FMO is defined in the H.264 / AVC standard, and it is possible to prevent an error occurring between the regions by dividing the image into a plurality of regions and encoding them. According to FMO, a plurality of rectangular slice groups can be specified, and the rest can be designated as a background slice group.

That is, the video stream synthesizing unit 103 modifies the process of dividing one image into a plurality of slice groups, and combines the plurality of slices into a plurality of slice groups, Other video streams can be synthesized.

The contents of the slice data, header, and image data described above will be described once again in FIGS. 4 and 5 below.

The transmitting unit 104 transmits the second single video stream to the device 30. For example, the transmitting unit 104 may transmit the second single video stream to the device 30 through a unicast transmission scheme. When the transmitting unit 104 transmits the second single video stream to the device 30, it can establish a session with the device 30 according to the RTSP standard.

Meanwhile, the transmission unit 104 may transmit the second single video stream to a video stream composition server (not shown), and then a video stream composition server (not shown) may transmit the second single video stream and the third advertisement video stream Can be synthesized and transmitted to the device (30). The transmitting unit may use a multicast or broadcast method to transmit the second single video stream to the video stream combining server (not shown). The transmitting unit 104 may provide additional information related to the generated single video stream or may transmit URL information to the device 30 for connection to a specific web site.

The video stream composition server 10 described in FIG. 3 may be referred to as a second video stream composition server or a local video stream composition server. In other words, the video stream composition server 10 can be used in combination with the second video stream composition server and the local video stream composition server. Hereinafter, the operation of the video stream generating server (not shown) can be inferred through the operations of the previous video stream generating server 20 and the video stream combining server 10, and thus a detailed description thereof will be omitted.

4 is a diagram illustrating an image divided into a plurality of regions according to an embodiment of the present invention. Referring to FIG. 4, the slice group of the second single video stream may be a slice group having a plurality of rectangular shapes according to a foreground / leftover method of FMO, The slice group and the slice group 2 can respectively have broadcast video streams. A slice group may be incremented to further synthesize a new video stream.
